Practice 1. The PSpice simulator. Time-domain filter analysis (2h)
In the first hour of the session, the PSpice circuit simulation tool is presented. This software is already known by the student of the subject Systems and Circuits of 1st year, but then the graphic interface was used for the making of the circuits and in these sessions the student is taught to use the commands to edit complete programs that describe the circuit and perform the desired simulation. In the second hour of the session, the student must write the PSpice code to perform a time-domain analysis of two filters and, in view of the results, draw conclusions about the nature of these and their possible applications. Pre-preparation time: 2 hours. Deliverables: each group must submit the answer sheet.
Practice 2. Frequency analysis of passive and active filters with PSpice (2h)
As a continuation of practice 1, the same passive filters are now analyzed, but in the frequency domain. In this way the student can understand why different output signals were produced in the time domain according to the frequency of the input signal. In the second part of the practice the student learns how to describe an operational amplifier through different models (ideal, semi-ideal and library model). Subsequently, the student must write several codes in PSpice to perform the frequency analysis of different active filters that incorporate these amplifiers. The student must determine the range of application of the different models of operational amplifier and draw conclusions about the behavior of the different filters after visualizing the Bode diagrams obtained in the simulations. Pre-preparation time: 2 hours. Deliverables: each group must submit the previous study and the answer sheet.
Practice 3. Equalizer design (2h)
In this practice, the study of active filters is carried out in depth and, in particular, a device with amplifying characteristics is designed, but with a slope in the transition zone of less than 20dB/decade. The design carried out here is not related to the general techniques of synthesis that are explained in block 3 of the theory program, but is based on the concepts explained in the theory classes of block 1. In a first part, the response of the filters that are intended to be designed must be studied: filter type, gains, cutting frequencies and slope in the transition zone. Subsequently, the design values of the different elements of the circuit that generate the desired response must be found. In the laboratory, the designed circuits will be simulated with PSpice and it will be verified that, indeed, they present the response that was intended to be obtained. Pre-preparation time: 2 hours. Deliverables: each group must submit the previous study and the answer sheet.
Practice 4. Synthesis of two-port networks. Implementation of a gyrator (2h)
Two devices are presented: the negative impedance converter (NIC) and the rotator. Through different families of quadrupoles, the student must learn how to implement a gyrator with different configurations from NICs and resistances. Afterwards, the student must simulate these configurations in PSpice, check the correct functioning and implement a filter, which under normal conditions would require a coil, without this using a gyrator. Finally, you must simulate this filter and obtain, from the Bode diagram of the module of its transfer function, the cutoff frequency of the filter. Pre-preparation time: 2 hours. Deliverables: each group must submit the previous study and the answer sheet.
Practice 5. Filter Design (2h)
As an application of the different synthesis techniques studied in block 3, the student is asked to design two filters using their corresponding masks. In the laboratory you must check, through simulations in PSpice, that the designs carried out actually meet the predetermined specifications. The results obtained will be compared according to the type of filter designed (Butterworth, Chebychef or Cauer). Pre-preparation time: 2 hours. Deliverables: Each group must deliver the pre-study and answer sheet.
Practice 6. Laplace Transform and Stability (2h)
The Laplace transform will be applied in the study of the stability of a circuit, based on the characteristics of the poles of the characteristic function (in the Laplace domain) of circuit transfer. Pre-preparation time: 2 hours. Deliverables: Each group must deliver the pre-study and answer sheet.
Promoting the continuous improvement of working and study conditions of the entire university community is one the basic principles and goals of the Universidad Politécnica de Cartagena. Such commitment to prevention and the responsibilities arising from it concern all realms of the university: governing bodies, management team, teaching and research staff, administrative and service staff and students. The UPCT Service of Occupational Hazards (Servicio de Prevención de Riesgos Laborales de la UPCT) has published a "Risk Prevention Manual for new students" (Manual de acogida al estudiante en materia de prevención de riesgos), which may be downloaded from the e-learning platform ("Aula Virtual"), with instructions and recommendations on how to act properly, from the point of view of prevention (safety, ergonomics, etc.), when developing any type of activity at the University. You will also find recommendations on how to proceed in an emergency or if an incident occurs. Particularly when carrying out training practices in laboratories, workshops or field work, you must follow all your teacher's instructions, because he/she is the person responsible for your safety and health during practice performance. Feel free to ask any questions you may have and do not put your safety or that of your classmates at risk.

In the case of justified absence in any of the practices, the teachers will enable a special recovery schedule after the completion of the last practice and before the end of the semester. All practices have the same value. They represent 30% of the grade of the subject and a minimum of 4 (out of 10) is required to average with the rest of the evaluation activities.

Practical laboratory assignment
For those who have attended all the practices, the final evaluation is carried out through their deliverables, with the same criteria as in the continuous evaluation. For those who have not attended all the practices, an exam will be held that will evaluate the learning process developed in the practices, with the same criteria as in the continuous evaluation. A minimum of 4 (out of 10) is required to average with the rest of the evaluation activities. The same criteria are followed in terms of competencies and learning outcomes assessed as in continuous evaluation.

Written and/or oral exams (assessment of theoretic and applied content and/or laboratory practice)
Two final examinations will be conducted, which are considered to be independent evaluation activities. The minimum grade to be able to average both final exams to each other will be 30% of their total value (3 out of 10). The final minimum grade of the average of both final exams, to be combined with that of the rest of the evaluable activities of the subject, will be 40% of its total value (a 4 out of 10). Each final exam will be composed of short questions of development of concepts related to theory (30%) and analysis and design problems (70%). The same criteria are followed in terms of competencies and learning outcomes assessed as in continuous evaluation. First final exam, equivalent to the first partial exam (units 1 and 2). Second final exam, equivalent to the second partial exam (units 3 and 4). Weight on the total score of each: 35%. If a student who has passed an assessment activity in the continuous evaluation system wishes to present himself to that same activity in the final evaluation system, he must renounce the qualification obtained in the continuous evaluation system.
70 %
The subject will be considered passed if the average grade in the exam-type assessments (70% of the total) is greater than or equal to 4 out of a maximum of 10 points and, in turn, the grade of the subject is greater than or equal to 5. Likewise, it will be a necessary condition to approve the subject, together with the one already mentioned, to obtain a minimum of 4 points in the evaluation of practices. In addition, it is mandatory in the continuous evaluation system: -Carry out all the proposed practices. -Deliver both the previous theoretical study and the report or answer sheet of the work done in the laboratory in each of the practices. The approved midterms are saved both for the final evaluation system and for the extraordinary call. If a student who has passed an assessment activity in the continuous assessment system is presented to that same activity in the final assessment system, he or she must waive the grade obtained in the continuous assessment system.
